Fish Oil Surprise

The
bottom line is that having fish oil capsules with your steak is
nonsense. Eating more fish really means eating much less of the
damaging meats and that is the source of the benefit. The best
advice is to fill up your freezer with fish and eat any other type of
meat elsewhere so that it becomes an occasional luxury.

In
the meantime, fish oil on its own is no help at all and need not be
bothered with. I had not been convinced myself and had not used
them. The manufacturers need to return to the drawing board with
this one.

At
least we are seeing science steadily at work now in the supplements
business. This weeds out a lot of perfectly good ideas that simply
do not fly. Welcome to science. Not all research is paid for by
drug companies.

Omega-3 fatty acids,
found in oily fish such as sardines and salmon and once touted as a
way of staving off heart disease and stroke, don’t
help after all, according to a Greek study.

Based on a review and
analysis of previous clinical trials including more than 68,000
participants, Greek researchers whose report appeared in the Journal
of the American Medical Association said the fatty acids have no
impact on overall death rates, deaths from heart disease, or strokes
and heart attacks.

This was true whether
they were obtained from supplements such as pills, or from fish in
the diet, said the researchers, led by Mosef Elisef at the University
Hospital of Ioannina.

"Overall,
omega-3...supplementation was not associated with a lower risk of
all-cause mortality, cardiac death, sudden death, myocardial
infarction, or stroke based on relative and absolute measures of
association,” Elisef and his team wrote.

A decade ago, medical
evidence suggested that boosting omega-3s, including the acids known
as EPA and DHA, with food or supplements had a strong protective
effect even though the mechanism wasn’t understood.

Scientists cited
improvements in levels of triglycerides - a type of fat in the blood
- as well as blood pressure levels and heart rhythm disturbances.

But since then, the
picture has grown clouded. Earlier this year, a group of Korean
researchers found that omega-3 supplements had no effect on heart
disease or death based on 20,000 participants in previous trials.

The current study
pooled results of 18 clinical trials that assigned participants
randomly to take either omega-3 supplements, or not. It also includes
two trials in which people got dietary counseling to increase their
consumption of omega-3 rich foods.

Because the trials in
the Greek analysis went as far back as 1989, researchers also
considered whether growing use of statins and other medications could
explain why later studies failed to support the earlier findings. But
Elisef and his team said that wasn’t the case.

Because people who eat
a lot of fish have been found to have less heart disease, researchers
figured that perhaps putting the supposed “active ingredients” in
a pill could provide similar benefits, said Alice Lichtenstein,
director of the Cardiovascular Nutrition Laboratory at Tufts
University in Boston.

“What we have
learned over the years is you can’t think about individual
nutrients in isolation,” she added.

People who eat fish
often may be replacing things like steak, hamburgers or quiche,
making for a healthier diet.

Instead of
supplements, Lichtenstein recommended eating fish at least twice a
week, having a diet rich in whole grains and vegetables, getting lots
of physical activity, and not smoking.

Thanx for Sharing such a hugefull information and lots of benifits of Fish Oil. ya u r ryt, Fish Oil is the one of the best nutrician , it has been show to provide a number of health benifits, and recomended by many health autorities as a part of balanced diet. Fish oil contains omega-3 fatty acids, specifically docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).One of the health benefits linked to Fish Oil is a low risk of heart attack. very healpfull for blood circulations.
